This webinar will describe the importance of environmental strategies and how they differ from individual-focused prevention programs. Environmental strategies are prevention interventions that address factors related to the context within which individuals make decisions about initiating and continuing substance use. Researchers have identified numerous risk and protective factors for engaging in substance use, which are often categorized by a socio-ecological model. Environmental strategies primarily seek to address factors found at the community and society levels of the model. The webinar will discuss the different types of environmental strategies and provide examples of evidence-based strategies. It will also walk through examples of collaborative partners needed to implement environmental strategies and the pre-implementation work that preventionists will need to complete.
